Do I Need a 200A Panel Upgrade? Signs & Cost Factors

Not every home needs 200-amp service — but a lot of homes that think they're fine are quietly running out of capacity. If you're adding an EV charger, a heat pump, or a hot tub, or you're fighting nuisance trips and a full panel, it's worth knowing the signs. Here's how to tell, and what actually drives the cost.

Signs you may need an upgrade

Any one of these is a reason to have your service evaluated. Several together usually means it's time.

• You have 60A or 100A service and want to add an EV charger, heat pump, or hot tub
• Your panel is full — no open slots, or "double-tapped" breakers sharing a slot
• Breakers trip when several big appliances run at once
• You still have a fuse box or a panel from an unsafe brand
• Lights dim noticeably when large appliances start
• You're renovating, adding square footage, or finishing a garage or shop
• A home inspection or insurer flagged the service as undersized or outdated

100A vs 200A — which do you need?

The honest answer comes from a load calculation, not a guess. We add up your real and planned loads so you don't pay for capacity you'll never use — or upgrade only to run short again.

What drives the cost

A panel upgrade isn't a single fixed price, because several factors vary house to house:

• Whether just the panel changes, or the full service entrance and meter base too
• The condition of the grounding and bonding (older homes often need updates)
• Whether the utility service is overhead or underground
• Any code corrections uncovered once the panel is opened
• Permit and inspection fees

If two or more of the signs above sound familiar, start with our panel upgrade service. Planning to charge a car at home? Pair it with EV charger installation. If your existing panel is a Federal Pacific or Zinsco unit, treat the upgrade as a safety priority.
